Abstract

A process for the production of flexible-elastic polyurethane (PUR) foam comprises reacting: (A) polyisocyanates or their prepolymers, (B) compounds with at least two isocyanate- reactive hydrogen atoms and a mol. wt. of 500-18,000, comprising (i) polyether-polyol(s) with a functionality of 4-8, preferably 5-7, and (ii) filler-containing polyol(s) of the polyurea dispersion- (PHD)-, SAN- or PIPA-modified type with a functionality of 2.5-4 (where PHD = , SAN = styrene/acrylonitrile graft, PIPA = polyisocyanate-polyaddition with alkanolamines), (C) optionally other reactive compounds (as in B) with a mol. wt. of 32-499, (D) water, (E) optionally blowing agents, (F) activators, stabilisers and other normal additives, and (G) alkanolamine crosslinkers of formula Hm((CH2C(R)HO)nH)3-m (I). In (I), m = 0-2; n = 1-3; R = H or methyl.
